Abstract: Computerized methods and systems for determining flow direction relative to a bidirectional pressure sensor are provided. The method includes receiving pressure information from the bidirectional pressure sensor. The method includes using the pressure information to evaluate, at a processing circuit, pressure at the bidirectional pressure sensor over time, The method includes assigning a flow direction to a current pressure of the bidirectional pressure sensor by comparing the current pressure to at least one past pressure.
